Abstract
A
methodology
was
developed
for
synthesizing
N-acyl-N'-sulfonyl
hydrazides
through
acyl
substitution
reactions
between
activated
amides
and
arylsulfonyl
hydrazides.
Optimization
of
the
reaction
conditions
revealed
that
using
Cs₂CO₃
as
a
base
1,4-dioxane
solvent
at
25
°C
12
hours
produced
highest
yields.
Among
various
tested,
N-benzoylsuccinimide
found
to
be
most
reactive,
with
reduced
reactivity
observed
N-mesityl-,
N-tosyl-,
N-Boc-substituted

N-acyl-N′-sulfonyl
yields
ranging
from
63%
